The chairs.

The object of the invention is to provide a chair having a fabric backand seat held under spring tension to prevent undue sagging of the same.

Another object of the invention is to provide a chair of this character,in which the back and seat can be readily removed, or applied, in orderto allow the fabric to be Washed or changed.

A further object of the invention is to provide a simple and comfortablechair which can be cheaply manufactured with certain details ofstructure and combination of parts hereinafter more fully described.

In the accompanying drawings,

Figure 1 is a vertical longitudinal sectional view of my improved chair;

Figure 2 is a sectional view, taken on the line 22 of Figure 1;

Figure 3 is a sectional view, taken on the line 33 of Figure 1;

Figure 4 is a sectional view, taken on the line 4-4 of Figure 2;

Figure 5 i a sectional view, taken on the line 5--5 of Figure 3;

Figure 6 is an enlarged sectional view, shOW- ing the spring and itsattachment to the seat of the chair.

Referring now to the drawings, l represents the front legs of theimproved chair, which have pivoted thereto, at 2, the obliquely arrangedrear legs 3 connected together at their rear ends by the transverse bar4. Pivotally connected to the upper ends of the front legs, at 5, arethe arms 6, which extend in a horizontal direction and pivotallyconnected at I to the obliquely arranged back members 8. The lower endof the back members are bifurcated, as indicated at 9, and adapted tostraddle a transverse bar It]. carried by the obliquely arranged rearlegs 3 whereby they are pivotally mounted thereon. The back members 8,as shown in Figure 1 of the drawings, extend a considerable distanceabove the arms 6, and extending around the same, above the arms, is afabric back rest I I. This back rest is, of a length to extend aroundthe back members 8 and is provided with hems l2 and I3, in which areinserted the wire looped members l4 and I5 having the kinked portions l5and I1, into which are hooked the ends l8 and I9 of the coil spring 29.The back rest ll, intermediate its upper and lower ends, is providedwith a fabric covering 2| to receive and protect the spring 20 and holdit in its proper position.

invention relates to improvements in The obliquely arranged legs "3extend beyond the front legs land are connected by a transverse bar 22.The back members B'are connected by-a transverse'bar-23 arrangedin'horizontal 5 alinement with the bar 22. The lower ends of the frontlegs I are connected by a transverse bar 24 to brace the same. By thisstructure, it will be seen that the bifurcated ends of the back membermay be lifted from the bar II] and the chair folded in a fiat positionby the arrangement of the pivots I, 5 and 2.

The seat 25 i made of a piece of fabric looped around the bars 22 and23, and provided with hems 26 and 21, into which pass the straightportions of the looped metal members 28 and 29. These members each havetheir free ends extending obliquely inwardly, a indicated at 30 and 3|,and are turned inwardly at 32 and 33, and have hooks 34 and 35 whichhook over the straight portion 31. The hems 26 and 2'! are provided withcut-out portions 38 and 39 to expose the straight portions, so that thehooks may be readily applied. Coil springs 40 and 4| are provided witheyes through which the looped members 28 and 29 pass, and whereby theyare drawn together at their outer ends. Coil springs 42 and 43 connectthe inner ends of the obliquely arranged portions 30 and 3|, so as toprevent the straight portions of the members 28 and 29 from bending andalso 30 to cause a greater tension on the fabric seat.

From the foregoing description, it will be seen that the back can bereadily placed over the upper free end of the back sections 8. The seatcan be readily removed by releasing the hooks 34 and 35 and sliding thespring 40, 4|, 42 and 43 from the members 28 and 29.

While I have shown a specific form and arrangement of spring connectedmember for drawing the back and seat tight, it will be understood thatthe same could be varied without departing from the spirit of theinvention.

Having thus described the invention, what I claim is:

1. A chair, comprising front legs, inclined rear legs pivoted to thefront legs and extending beyond the same, back members pivotallyconnected to the rear inclined legs, a back carried by the upper end ofthe back members, arm rests pivotally connected to the upper ends of thefront legs and the back members, a transverse bar connecting the backmembers, a transverse bar connecting the upper ends of the inclined legsbeyond the front legs, and a fabric seat extending around the transversebars and connected to- 65 gether by a spring device.

2. A chair, comprising front legs, inclined rear legs pivoted to andextending beyond the front legs, back members pivoted to the inclinedlegs intermediate their ends,arms pivotally connected to the upper endsof the front legs and to the back members, a transverse bar connected tothe back members, a transverse bar connecting the inclined rear backlegs forwardly beyond the front legs, a seat of fabric extending aroundthe transverse bars, and. spring tensioning means connecting the ends ofthe fabric.

3. A chair, comprising front legs, inclined rear legs pivoted to andextending beyond the front legs, back members pivoted to the inclinedlegs, arm pivotally connected to the back members and the upper ends ofthe front legs, a transverse bar connecting the back members, atransverse bar connecting the inclined rear leg forwardly beyond thefront legs, a fabric seat extending around the transverse bars andhaving its ends provided with hems, loop members extending within thehems, and coil prings removably connecting the looped members.

4. A chair, comprising front legs, inclined rear legs pivoted to andextending beyond the front legs, back members pivoted to the inclinedrear legs, arms pivotally connected to the back members and the upperends of the front legs, a transverse bar connecting the back members, atransverse bar connecting the inclined rear legs forwardly beyond thefront legs, a fabric seat extending around the transverse bars andhaving its ends provided with hems, loops held within said hems andprovided with converging arms forming eyes, and a coil spring removablyconnecting the eyes.

5. A chair, comprising front legs, inclined rear legs pivoted to andextending beyond the front legs intermediate their ends, back memberpivoted to the inclined rear legs, arms pivotally connected to the backmembers and the upper ends of the front legs, a transverse barconnecting the back members, a transverse bar connecting the inclinedrear legs forwardly beyond the front legs, and a fabric seat extendingaround the transverse bars and having it ends connected by a yieldingmember.
